Abstract

A simple method for anchoring nickel particles on chemically functionalized carbon nanotubes using nickel(II) nitrate hexahydrate is described. The functionalization is accomplished in three main steps and leads to carbon nanotubes with nickel nanoparticles attached on the walls. The structural properties of the resulting material were characterized by X-Ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM), while their magnetic properties were measured at room temperature using a vibrating - sample magnetometer. The results obtained are discussed..
